/* PocketPlay tools network, kit v2 site CSS.
   Loads after /_kit/v2/pp.css and uses only its tokens. Three jobs:
   1. page furniture for tool pages and the hub / sub-site homes,
   2. a compatibility layer that maps the original tool vocabulary (.panel, .btn-primary, .dropzone, .input …)
      onto kit v2 so every tool keeps its DOM, ids and scripts while looking like the rest of PocketPlay,
   3. old custom-property names (--panel, --fg, --muted …) aliased to kit tokens for the 120 inline <style> blocks. */
